2004 C240 4 Matic
Exclamation HELP PLEASE C240

Hi everyone...new member here. Just spent all my money to by a 2004 C240 4 Matic from a guy who seemed trust worthy! Afterwards I smelled gas on day 1. I brought it to a Mercedes dealer and they said it was the sending unit. They wanted $1700 to fix!! Don't have it so this girl is going to attempt changing it herself! I bought the unit and it will be here Wednesday. Can anyone tell me where it is located? I saw a video that said it was behind the back seat...? Is that true? Thanks! Any help with this adventure would be appreciated! Tutorial?

I looked it up and it is the in tank unit. The w211 pump is the same setup and there are tones of threads about changing it since it was a faulty part from the factory. Unfortunately our cars were not covered in the recall. I just did this on mine so if you get stuck let us know.

You've been on the forums for a while, and have had an MB for a while.
Yet, you didn't give critical important information.
???

What year is the car?
What engine is in the car?
What country is the car in/from?

The M271 4-cylinder has a problem with the "$17 hose" under the intake.
Actually, all of those hoses should be changed.
For a DYI, also use thermo-shield on the hoses. Imho, the dealerships should do that also.

Fwiw, hoses deteriorating from heat is common in "older" cars (10+ years).
Often, it's from the lack of proper heat shielding from the factory - to save money.
